  2. 1. Silicon neural interfaces -Design and biomedical aspects-

    Author : Lars Wallman; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; pn-etch stop; biocompatibility; neural recordings; porous silicon; silicon; neural interface; sieve electrode; General biomedical sciences; Biomedicinska vetenskaper allmänt ;

    Abstract : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

  6. 4. Development of a polymer based neural probe - How to record intracortical neural activity while minimizing the tissue response

    Author : Fredrik Ejserholm; Avdelningen för Biomedicinsk teknik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural Probes; Electrode Modification; Polymer; Neurophysiology; OSTE ;

    Abstract : Intracortical neural probes have in the last couple of years been developed from stiff single probes to stiff multi-electrode neural probes to flexible multi-electrode neural probes. One reason for the change in design is that more than one recording/stimulation electrode, as in the case with a single wire, is needed for more advanced studies. READ MORE

  7. 5. Neural control of standing posture

    Author : Craig Tokuno; Andrew Cresswell; Alf Thorstensson; Marc Carpenter; Thomas Sinkjær; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Medicin Teknik; Medicine Technology; Posture; motor cortex; electromyography; kinematics; H-reflex; pre-synaptic inhibition; transcranial magnetic stimulation;

    Abstract : When humans are asked to stand normally, they are not completely motionless. Rather, small amounts of body movement, termed postural sway, can be observed. Although the postural sway of standing has been well described, the manner in which this sway is neurally controlled and its influence in tasks involving postural re-stabilization are not known.
